net: remove useless pfmemalloc setting
When __alloc_skb() allocates an skb from fast clone cache, setting pfmemalloc on the clone is not needed. Clone will be properly initialized later at skb_clone() time, including pfmemalloc field, as it is included in the headers_start/headers_end section which is fully copied.

DT with the MMU off may result in alignment faults. So fix the situation by moving the update_fdt_memmap() call into the callback function invoked by efi_exit_boot_services() right before it calls the ExitBootServices() UEFI service (which is arguably a better place for it anyway) Note that disabling the MMU in ExitBootServices() is not compliant with the UEFI spec, and carries great risk due to the fact that switching from cached to uncached memory accesses halfway through compiler generated code (i.e., involving a stack) can never be done in a way that is architecturally safe.
